526 on rIfx (genCmp was broken)
528 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
530 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
531 * src/z80/main.c (_keywords[]),
532 * src/SDCCglobal.h (struct options),
534 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
535 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
536 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
537 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
538 always available in leading double underscore form. The C99 support is
539 mostly missing, but it's a start.
540 * support/regression/tests/bug-227710.c: fixed nonconforming use of
541 reserved identifier "__data".
543 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

619 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
621 * device/lib/printf_large.c: removed inline assembly for portability and
622 readability. Use printf_fast if speed or size are more important.
623 * src/pic16/gen.c: removed conditions around use of DEBUGpc
624 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
626 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
628 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
629 prevent compiler warning
631 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
633 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
634 moved to level 0 and declared as static. Also they are explicit
635 placed in access bank. This was necessery because some times they
636 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
637 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
638 optimizations. Currently only compare to unsigned char is implemented,
639 * src/pic16/gen.c: added fReturnIdx array,
640 * (struct resolvedIfx) is moved to gen.h and made public,
641 * (struct _G): added sregsAlloc and sregsAllocSet fields,
642 * (aopForSym): added an optimization to directly store in stack of
643 the operand of a SEND iCode,
644 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
645 but as registers instead (AOP_REG) using the fReturnIdx array,
646 * (pic16_freeAsmop): remove the freed register from the
648 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
650 * (pic16_popGetTempRegCond): changed function prototype, now
651 function takes also a bitVector argument v which holds the current
652 set of registers that are allocated for stack access by aopForSym,
653 registers allocated in aopForSym for accessing stack symbols are not
654 any more part of the functions usedRegs field,
655 * (genCall): some times aopOp is called for a stack variable to be
656 send, aopForSym might perform the push, if this is true make sure
657 that genCall doesn't push the variable twice by testing _G.resDirect,
658 * (genFunction): changed testing for unspecified interrupt number
659 from 256 to INTNO_UNSPEC,
660 * modified selection scheme of frame pointer generation. Previously
661 if function did use local registers a frame pointer was generated,
662 now a frame pointer is generated only if function has arguments
663 (that need PLUSW2 register access), or has stack arguments, or the
664 compiler is not instructed to omit the frame pointer,
665 * (genEndFunction): before restoring local registers that were saved
666 in the function preamble, also restore the registers that *might*
667 have been allocated for stack access,
668 * (genRet): removed some old comments,
669 * (genCmp, the active (RN's) version): added a call to the
670 pic16_genCmp_special function to perform the compare with a more
671 robust and optimized way,
672 * (genInline): a feature has been added in inline code generation,
673 which allows a wildcard variable substitution when writing inline
674 assembly. Code is incomplete and experimental therefore undocumented,
675 * (genCast): changed order of aopOp for result and right to allow
676 aopForSym to directly load the result if possible,
677 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
678 perform an optimized compare on some selected special occasions,
679 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
680 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
681 generate an IVT any more,
682 * src/pic16/main.c (pic16_optionsTable): added command line option
684 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
685 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
687 * src/pic16/NOTES: Raphael Neider added in list of active developers
688 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
689 jumptable_end to prevent bug #,
690 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
691 inCond and outCond fields,
692 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
693 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
694 turn off register spilling,
695 * (packRegsForOneUse): synced with other ports' versions although it
696 is not used currently,
697 * (pic16_packRegisters): added an optimization while reading
698 structure bitfields, some registers may be saved (malloc code is
699 decreased by 80 bytes)
701 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
703 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
704 left is a bitfield, if yes, then don't optimize assignment. Perhaps
705 this can be optimized more?
707 2005-03-10 Raphael Neider <rneider AT web.de>
709 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
710 genNearPointerGet): (hopefully) fixed access to bitfields via
711 pointers (p->bitN = x; and x = p->bitN; failed)
713 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
715 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

901 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
902 this might fix SIGSEGVs on MinGW...
903 * src/SDCCopt.c (killDeadCode): restored original behaviour
904 (volatile operands might get thrown away though)

1343 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1345 Adding support for replacing ljmps with sjmps in jumptables
1346 generated for switch statements. For now you need to set the
1347 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1348 Now 4 algorithms for mcs51 jumptable generation are used:
1349 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1350 addresses loaded pc-relative for up to 112 cases and stack-pushing
1351 target addresses loaded with offset from dptr for up to 256 cases.
1353 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
1354 * src/mcs51/main.c: adapted constants for switch table generation
1355 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

1375 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
1377 Large cummulative patch for pic16 port.
1378 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1379 to call when a stack overflow occurs,
1380 * (malloc.h): added CVS Id tag,
1381 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1383 * added libc directory. The current version of LibC contains string
1384 functions, ctype functions and macros and some functions of the
1385 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1386 be extensively tested in the future. Standard disclaimer here.
1387 Library is not automatically build yet. But one can build it by
1388 invoking 'make' inside the libc directory.
1389 * added ADC library under libio. Preliminary version yet.
1391 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
1392 * src/pic16/gen.c (aopForRemat): asmop size is filled by
1393 aopForRemat() now and not by pic16_aopOp(),
1394 * (pic16_popGetTempReg): removed warning messgae when allocating
1395 temporary registers, its a buggy feature and will be removed,
1396 * (pic16_popGet): set register instance field in AOP_CRY,
1397 * (pic16_outBitC): fixed for results in size greater than 1,
1398 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1399 * (pic16_storeForReturn): optimized return of 0,
1400 * (genCmp): experimental code for new genCmp which uses PIC18's
1401 special compare&skip instructions. Initial tests fail some times
1402 with variables grater than 1 byte in size, so new code is disabled,
1403 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1405 * (genCast): began a fix to optimize the casting of a bit to another
1406 bit, now assigning a bitfield to another bitfield will fail, sorry,
1407 * src/pic16/main.c: disabled the use of lr-support feature,
1408 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
1409 * added some function prototypes, added function _debugf prototype,
1410 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
1411 bits with offset (case PO_GPR_BIT),
1412 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1414 * (isBankInstruction): modified to return 0 for no banking instruction,
1415 and 1 for banking instruction,
1416 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1417 caused stop processing pCodes after a inline assembly block,
1418 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1419 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1420 registers when it shouldn't,
1421 * src/pic16/ralloc.c (allocReg): add preliminary support for
1422 supporting a limited set of temporary registers,
1424 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1426 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1427 genDataPointerSet): ensure assignments always copy in MSB to LSB
1429 (loadRegFromAop): recognize CLRH optimization,
1430 (genFunction): optimize RECEIVE iCodes in reentrant functions
1432 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1434 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
1435 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
1437 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

1443 * device/lib/_gptrget.c (_gptrget),
1444 * device/lib/_gptrgetc.c (_gptrgetc),
1445 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
1446 instead of sjmp to ret
1447 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
1448 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
1450 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

4432 loaded with the linker search paths (-L arguments) and the libraries
4433 to be linked with the current source (-l arguments). Changes
4434 currently will affect only the pic16 port.
4435 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4436 include path the port specific paths and port specific libraries,
4437 * gplink command now contains the $3 argument,
4438 * src/pic16/device.h,
4439 * src/pic16/device.c,: structure PIC_device is made public and
4440 renamed to PIC16_device, the same for variable Pics which is renamed
4441 to Pics16. Updated all references to them.
4442 * src/pic16/glue.c (pic16glue): corrected bug with code
4443 initialization which bypassed the variable initializations block.
4445 * device/lib/pic16/Makefile.rules: removed --penable-stack from
4446 COMPILE_FLAGS and added the --nostdinc option
4448 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4450 * device/include/mc68hc908jb8.h: Register defs for another member
4451 of the hc08 family. Contributed by Bjorn Bringert - thanks!
4453 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4455 Documenting changes from previous commits.
4456 * configure.in (version 1.56),
4457 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4458 when generating output files to configure the pic16 library,
4459 but now I've commented it out, since gputils aren't installed in the
4460 SF compile farm, so library won't compile
4462 * device/lib/Makefile.in (version 1.56): initially I've added in
4463 target 'all' the prerequestive 'model-pic16' so it compiled the
4464 pic16 library, but now I've commented it out for the same reasons
4466 * added targets 'model-pic16' and 'objects-pic16' to compile the
4468 * added target 'port-specific-objects-pic16' to handle the
4469 generated libraries and copy them into the build/ directory
4470 * added target 'clean-intermediate-pic16' to clean intermediate
4471 files into pic16 directory
4472 * in target 'installdirs' added line to create directory pic16 in
4473 the installation path
4475 * device/include/Makefile.in (version 1.11): in target 'install'
4476 added lines to copy all header files to installation path,
4477 * in target 'installdirs' added line create directory for pic16
4478 headers in the installation path

4493 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4494 option so that it actually works. Made it specific to the z80, since
4495 the gbz80 doesn't have these kinds of I/O ports.
4497 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4499 * device/include/z180.h,

4512 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4514 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4515 changed interrupt vector table generation to only emit declared vectors.

4521 Mainly changes to support compilation of the device libraries
4522 * src/pic16/device.c: stack is allocated via symbol and not
4523 via literal number. The symbol is placed in the corresponding
4524 position of the data ram
4525 * (pic16_dump_section): relocatable and absolute uninitialized
4526 data are now emitted in sorted order to reduce section naming,
4527 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4528 weren't marked as being in the access bank,
4530 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4532 Added portion of GNU PIC Library under the directory
4533 device/include/pic16 and device/lib/pic16. These files
4534 contain the declarations of SFRs for the PIC18Fxx2 devices.
4535 The directory is initialized via configure from toplevel.
4537 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4539 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4540 the spilllocations to be compared correctly
4542 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
4544 * src/SDCCast.c (decorateType): fixed bug introduced today
4546 2004-01-12 Borut Razem <borut.razem AT siol.net>

4562 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4564 * doc/sdccman.lyx: Moved and added some sections, small changes
4565 all over. Telling LaTeX to be less strict with word spacing
4566 to better keep the right margin. Changed some notes about
4567 maintainance of the ports in section 3.2.1 - is it OK like this?
4569 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4606 UPPER for immediate operands,
4607 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4609 * src/pic16/peeph.def: all peepholes with movff are commented out,
4610 because there is a problem in the pcode peep optimizer,
4611 * src/pic16/ralloc.c: the register allocator can now reuse local
4612 function symbols for another function. This saves register usage.
4613 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4615 Added file src/pic16/NOTES with information about program writing on
4616 the current port version.

4625 * src/SDCCmain.c : fixed #872250: -l command line defined library
4626 files are scanned before standard library files
4628 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4645 gen51Code): more efficient parameter receive for --model-large
4648 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4651 * src/z80/main.c: added missed needLinkerScript flags (more than
4652 one port structure defined in these file)
4653 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

4669 needLinkerScript flag
4671 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4672 * src/pic/glue.c: added variable udata_section_name to
4673 override default uninitialized data segment definition for
4674 devices only with SHAREBANK memory (reported from Erik Epetrich)
4675 * (pic14emitOverlay): modified to emit a commented overlay segment
4676 directive when no overlay data exist
4677 * (picglue): modified to emit uninitialized data segment
4678 according to udata_section_name

4688 2004-01-07 Borut Razem <borut.razem AT siol.net>
4690 * support/scripts/sdcc.nsi: update PATH
4691 * support/scripts/sdcc.ico: craeted
4693 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>

4696 * doc/Makefile: fix install
4698 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4700 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
4702 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

4704 include information about variables allocated to the overlay
4707 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4709 * as/mcs51/lkmain.c: Help about -Y option

4721 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4723 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4724 (default behaviour).
4726 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4728 A python script to validate compiler diagnostic messages. It can be
4729 used to verify that sdcc complains about bad c source code and
4730 gives a good location of the error.
4731 * support/valdiag/Makefile,
4732 * support/valdiag/valdiag.py,
4733 * support/valdiag/tests/*
4735 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4737 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

4746 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4748 * src/common.h: added ifndef/define/endif macros
4749 around the header file.
4750 Bug reported from Jesus Calvino-Fraga
4752 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4754 * sdcc.spec: updated
4755 * device/include/Makefile.in: don't install CVS directories
4756 * device/lib/Makefile.in: added removal of CVS directories after install
4757 * doc/Makefile: fixed install, added local_icons
4758 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4759 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4760 * src/ds390/gen.c (genRightShift): fixed bug #870788
4761 * src/SDCCast.c (decorateType): fixed bug #870781
4763 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4765 PIC16 port related changes:
4766 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4767 added variable stackPos,
4769 * gen.c: genCall, assignResultValue: added support for
4770 pushing/retrieving function parameters to/from stack,
4771 genFunction,genEndFunction: setup stack frame for the
4773 genAddrOf: will be changed according to bug 863624
4775 * added files genutils.c and genutils.h which contain gen*
4776 debugged and optimised functions extracted from gen.c
4778 * glue.c: added variable 'externs' which holds extern symbols,
4779 pic16emitRegularMap: is modified to properly handle relocatable
4780 symbols under the new scheme,
4781 pic16createInterruptVect: is modified
4782 pic16printPublics: is modified to emit 'global' assembler directives,
4783 added pic16_printExterns to print extern symbols,
4784 pic16glue: initializes stack/frame pointer in the beginning of
4785 the assembly output. Temporary hack, will be corrected later,
4786 because gplink yet does not support stack and SDCC does not
4787 yet support a type of crt0.o object to create the final binary.
4789 * Removed many lines that contain 8051 legacy code.
4790 * The code is finally placed under a 'code' directive.
4791 * Added port specific options.
4793 * _process_pragma: simplified since now we do not need *special*
4794 include file to define SFR registers. But a separate header
4795 will be needed. This will be developed later.
4796 * _pic16_parseOptions: added, parses port specific options:
4797 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4798 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4799 --preplace-udata-with=
4801 * _pic16_setDefaultOptions: modified to initialize section names,
4802 but hack is temporarly out of order since it needs improvement.
4803 * _pic16_genAssemblerPreamble: configuration words are emitted by
4804 their address instead of their name. This part is incomplete and
4805 supports only the 18Fxx2 devices. Other devices will emit an error
4806 during assembly since they do not contain the same set of config
4808 * _pic16_genIVT: is modified,
4810 * pcode.c: added definitions for some hardware registers that are needed
4812 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4813 All PCI entries are updated. Now LFSR is supported.
4814 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4815 * added pic16_newpCodeOpLit2 to support instructions with
4816 two literal arguments
4817 * pic16_pCode2str: corrected code that emits assembler instructions
4818 with two literal operands and those that have an access bit modifier
4819 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4820 this fixes a bug which caused some labels to be lost, when an
4821 assembler directive was added, i.e. banksel,
4822 * pic16_FixRegisterBanking: improved logic that causes the insertion
4824 * InlineFunction: functions that are called once, are not any more
4825 inlined. This can be a port option in the future,
4827 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4829 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4830 hold the corresponding uninitialized symbols,
4831 * pic16_allocProcessorRegister: registers have explicit marked the
4833 * pic16_allocInternalRegister: registers are explicit marked as
4835 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4836 processing list, so bit registers were lost,
4839 * ralloc.h: added field 'accessBank' and original symbol operand
4840 in register definition,
4841 * removed the field isMapped from register definition,
4843 ** Several functions have been removed from various sources:
4844 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4845 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4846 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4847 pic16_assignRelocatableRegisters
4849 ** others have been introduced:
4850 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4851 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4853 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4855 * support/scripts/inc2h.pl: changed definition of BIT_AT
4856 to emit 'sbit at' instead of 'bit at'. This was a request.
4858 PIC16 port related preliminary changes:
4859 * gen.c: prefixed function popRegFromString with
4860 pic16_ and all references to it corrected
4861 * pcode.c: all pic16_pc_* hardware registers prefixed
4862 with underscore (_),
4863 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4864 * ralloc.c: newReg(): when register is REG_SFR then
4865 set address to rIdx,
4866 pic16_allocProcessorRegister(): marks register wasUsed=0
4867 pic16_writeUsedRegs(): added a call to assign processor
4868 registers via pic16_assignFixedRegisters
4870 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4872 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4873 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4874 variables in unused register banks. Also the SSEG is placed
4875 wherever there is enough space for it, and IDATA can be anywhere
4876 in internal RAM. For now compile using -Wl-Y[stack_size].
4877 The mem file is different for this option as well, since it
4878 makes no sense of talking about DSEG lenght.
4880 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4882 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4883 in certain cases, e.g. when ROM assignment, patch provided
4884 from Albert den Haan.
4886 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5929 A few small changes that speed up the peephole optimizer.
5933 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5935 Try to make the peephole optimizer smarter by maintaining
5936 an association between the assembly source code and the
5937 iCodes that originated them. Put this information to use
5938 with a new peephole rule condition "notVolatile" so that
5939 the rules can be aggressive yet still safe.
5944 * src/mcs51/peeph.def
5946 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5950 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5951 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5952 if the left or right operand symbols have the accuse flag set.
5954 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5956 Changed the type of the result of the ! (NOT) operator to char;
5957 previously it returned the same type as the source. This allows
5958 us to eliminate all the genFloatNot functions (all of its target
5959 implementations were very buggy) since !float can use the same
5962 * src/SDCCicode.c (ast2iCode): ! returns char

5971 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5972 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5973 during interrupts. Ensure WSAVE is located at a shared bank address.
5974 2. Fixed page selection in some places
5975 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5976 the registers name strings.
5977 4. Fixed "signed / unsigned compare" compiler warnings.
5978 5. The PIC port manages its own allocation of the general purpose
5979 registers, but makes no attempt to reuse them. As a result when
5980 compiling it soon runs out of general purpose registers. Some
5981 additional code was added to the files pcode.c and device.c to walk
5982 through the function call tree and rename the registers so that they
5992 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5993 genPlus() & genMinus() when the result is the same as left or right

5999 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6001 Made bitfield a distinct type from bit so that bitfields
6002 convert as per ANSI C and bits retain their traditional
6003 boolean style behaviour. Implemented bitfield support in
6011 * src/ds390/gen.c: bit v bitfield split
6012 * src/z80/gen.c: New support for bitfields
6013 * support/regression/tests/bitfields.c: reenabled z80,
6016 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6018 Rules 246.x, 247.x relate to bitfields, the others speed up
6019 access to xdata mapped I/O devices.
6021 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6023 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6025 Cleaned up genPackBits and genUnpackBits and added two helper
6026 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6027 for literal assignments in genPackBits (thanks to Frieder for
6033 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6035 Fixed bug #748310 (pointer to function type mishandled when the
6036 function name is omitted). Also fixed a SIGSEGV when a function
6037 attribute (reentrant, etc) is used on a non-function or on a
6038 function but misplaced before the parameter list.
6040 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6042 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6065 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6067 Made the constant following the "interrupt" keyword optional. If
6068 omitted, the function will not automatically be given an entry
6069 in the interrupt vector table (similar to #pragma NOIV, but
6070 less syntacticly kludgy). The interrupt number is also now
6071 range checked. Also fixed a bug in the high order bit example

6512 condition and ignore commands.
6514 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6516 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
6517 is in parts still quite out of date, I did changes as far as I felt makes sense
6518 for a non-native english speaker.
6519 Please feel free to add to the manual or to correct my changes.
6520 * doc/Makefile: undid touching the date of intermediate tex files.
6522 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6539 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
6540 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
6541 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
6542 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
6545 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6547 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6548 the regression tests I'm not brave enough to enable 245.b, 245.c
6549 * doc/sdccman.lyx: added latex preamble for hyperref package.
6550 Using pdflatex this will give you a hyperlinked pdf file with
6551 bookmarks. (prepend '%' before /usepackage if this breaks something)
6553 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

6567 Applied patch from bug 737905 (renamed yylineo to mylineno):
6574 * src/pic16/pcode.c: Cleaned warnings
6575 * src/pic16/pcodeflow.c: Cleaned warnings

6589 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6591 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6592 it can be defined with CFLAGS when running configure
6593 * src/SDCCmain.c: fixed compiling + linking with object files
6595 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6597 * configure.in: configure for pic16 port,
6598 added --disable-pic16-port
6599 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6600 * src/SDCCmain.c: linkOptions is changed to set *,
6601 added if/endif conditional macros to remove options help
6602 messages from optionsTable when a port is not configured, added
6603 support for the PIc16 port in the ports table, when executing
6604 the compiler with no port specified on command line, a default
6605 port is selected with the new macro DEFAULT_PORT which is
6606 defined in port.h, in setDefaultOptions() linkOptions is removed
6607 from initialization assignment, since now it is a set,
6608 parseCmdLine uses setParseWithComma for linkOptions, in
6609 linkEdit() linkOptions are accessed with new function indexSet()
6610 which returns the i'th item of a set variable. See SDCCset.c, in
6611 linkEdit() when calling buildCmdLine(), added linkOptions as
6612 last argument. Now users can pass arguments to gplink via the
6613 -Wl option, main() uses pic16glue() to glue up pic16 programs
6614 * src/SDCCpeeph.c: various changes to support pic16
6615 * src/SDCCset.c: added function void *indexSet(set *, int) to
6616 return the i'th item of the set

6621 added macro DEFAULT_PORT
6622 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
6623 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6625 * src/pic16/glue.c: commented out some error producing lines
6626 * src/pic16/main.c: __config directives are commented out to stop
6627 gpasm complaining and test the linkage with gplink, _linkCmd and
6628 _asmCmd changed to be more gplink and gpasm friendly
6629 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6630 produced an error when parsed, peep rule 12 is added to utilize
6631 movff, but it is commented out since the pCode does not support
6632 yet a command with 2 address arguments
6634 2003-05-18 <johan AT balder>
6636 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6637 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6656 on entry now. Add tbreak. Other enhancements and fixes for use
6659 2003-05-12 Borut Razem <borut.razem AT siol.net>
6661 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6663 2003-05-11 Borut Razem <borut.razem AT siol.net>
6665 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6666 the path of bin directory, so that PATH is the only env. variable, which has to be set
6667 in case of standard installation.
6668 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7697 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7699 * in \sdcc\as\mcs51\ changed these files in order to create an
7700 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7701 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7702 following files to include the previous two files: aslink.dsp,
7703 Makefile.aslink, Makefile.bcc, and Makefile.in.
7705 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7706 .adb instead of .cdb
7708 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7710 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7711 value from option --iram-size.
7713 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7715 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7718 2002-09-18 <wiml AT hhhh.org>
7720 * SDCClrange.h: exposed setFromRange() and setToRange()
7721 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7722 packRegsForAccUse() (bug 542397)
7723 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7724 multiple times and emitting the fetch operations more than once
7725 added aopGetUsesAcc() function to allow binary operators to
7726 fetch their operands in the correct order; made genMinus() emit
7727 compact code for X = LITERAL - Y
7729 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7730 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7731 sprintf() in line 1267.
7733 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7734 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7737 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7738 Changes to aslink (All the changes are marked with 'JCF'):
7740 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7743 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7744 area BSEG. Also moves, if possible, the DATA area down into the internal
7745 ram so more space is available.
7747 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7750 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7751 not bytes. Function summary() which creates a memory usage summary
7752 file with extension .mem. Reports of overlaping stack and small stack
7753 size. If the space for the stack is less than 16 bytes aslink trows a
7756 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7757 the 8051. Option 'y' for memory summary output file.
7759 Changes to sdcc (All the changes are marked with 'JCF'):
7761 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7763 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7764 overlaying area for it (uses RegBankUsed[4]).
7766 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7767 bank zero as used by default. By default aslink locates the stack
7768 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7769 the creation of the .mem file. Delegates the allocation of data area
7770 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7771 the begining of the stack area to aslink.
7773 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7774 glue() in SDCCglue.c creates an area for it.
7776 2002-09-03 Borut Razem <borut.razem AT siol.net>
7777 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7778 sdcc/src/pic/glue.c:
7779 introduced atexit() handler for teporay files removal in case of
7780 errors, assertions, ...
7782 2002-08-29 Borut Razem <borut.razem AT siol.net>
7783 * sdcc/support/cpp2/auto-host_vc_in.h:
7784 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7785 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7786 Maybe there is a similar problem with BORLANDC? It should be checked!
7788 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7789 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7790 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7791 was not executed, and the compiler (cl) launched a warning:
7792 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7794 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7795 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

7807 - added Release configuration in VS projects
7808 - review of compiler an linker options
7809 - VC .exe files are generated in bin_vc directory, not to interfere
7810 with binaries generated from other projects (cygwin, mingw, bcc ...)
7812 * sdcc/src/yacc.dsp: added
7814 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7815 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7816 and insert the version number definitions from .version
7818 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7820 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7824 removed from CVS, generated automatically
7826 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7827 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7829 2002-08-11 Borut Razem <borut.razem AT siol.net>
7830 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7832 2002-08-10 Borut Razem <borut.razem AT siol.net>
7833 * src/SDCCmain.c (main):
7834 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7835 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7836 The consequence was that some temporary files were not removed.
7839 unification of code in functions tempfilename() and tempfile():
7840 function tempnam() is defined in Visual Studio 6.0 and .NET
7842 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7844 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7845 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7846 - removed compiler command line option /WX: Treats all warnings as errors
7847 - update a list of source files, included into the project
7849 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7850 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7851 changed project type to Generic Project so that can be correcly converted to VS.NET project
7853 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7855 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

7859 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7860 added return 0 statements after assert() to make compiler happy
7862 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7863 added newline in the def file to keep MSC compiler satisfied
7865 * sdcc/src/z80/gen.c:
7866 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7867 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7868 - solved MSC error in function aopDump()
7870 * sdcc_vc.h: define PREFIX as "\\sdcc"
7872 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

7928 were not getting allocated.
7930 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7933 Fixed left shift. Will promote the left side of a left shift
7934 if a) left shifting more than size of operand or b) when assigned
7935 to something size > size of left side
7937 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8047 * sdcc/src/SDCCloop.c:
8048 Previous fix was not good. basic blocks that have "break" or "return" are
8049 not really partof a loop , but live ranges used in these blocks should
8050 be live thru the entire loop, so set partOfLoop but don't add them to
8053 2002-02-21 <johan AT FRIJA>
